    There are two main reasons to use one. The first is to add a toilet to a space that might only have access to a sink drain because these are compatible with those. The other is basements where the unit might have to flush up to the drain pipe.

    FYI: I am not a plumber. I found these while researching how to add a bathroom to my basement.
